Not really for the TT..but for what you put in the TT. I learned this years ago in Boy Scouts and thought I would pass on this simple mod. If you carry around a Saw in your TT see below:
Tubing covering saw blade
I used a piece of 3/4" automotive tubing and cut it right down the middle and it slips right over the saw blade protecting it from ruining your blade and also from cutting anyone. Just a cheap slick Mod...
